Butterfly

As Lepidoptera, butterflies have four wings, but unlike moths, the fore
and hindwings are not hooked together, permitting a more graceful flight.
A butterfly has six legs; the larva also has six true legs and a number
of prolegs. After it emerges from its pupal stage it cannot fly for some
time because its wings have not yet unfolded. A newly emerged butterfly
needs to spend some time 'inflating' its wings with blood and letting
them dry, during which time it is extremely vulnerable to predators.

Many species of butterfly are sexually dimorphic. Some butterflies, such
as the Monarch butterfly, are migratory.

Butterflies are often confused with moths, but there are a few simple
differences between them, including colour, habits, and pupating appearance.

Butterflies live primarily on nectar from flowers. Some also derive nourishment
from pollen, tree sap, rotting fruit, dung, and dissolved minerals in
wet sand or dirt. Butterflies are also pollinators
